I've successfully done the same thing with a 50ft tower. It's a lot of
work to install. There will be a lot of weight on that bearing just
above the rotor. Might be easily to just hire someone to swap out the
rotor when it fails. Just depends on how much time you want to put into
the project. For a hundred foot you might want to start out with a
larger diameter for the first 50ft and consider installing a brake at
the top to limit the twist on that 100ft of pipe when it gets windy.
Then again some will say the twist will save your antennas, so at least
with the brake as an option you can decide for yourself.

Subject: [TowerTalk] Rotator at bottom of tower
I am "considering" the possibility of running 105 feet of pipe extending
the existing mast to near ground level and mounting the rotator at that
location. The antenna is 20M5L48. I have to take the rotator down
because of a maintenance issue anyway and thought that in the long run
it might be nice to have the rotator low to the ground.
